Towards Sustainable Water Use: Factors Influencing Farmers’ Participation in the Informal Groundwater Markets in Pakistan

Abstract

Informal groundwater markets have spontaneously developed in Pakistan due to the heterogeneity of farmers’ resource endowments, irrigation water shortages, and productivity gains of groundwater. Evidence shows that water allocation through formal or informal water markets can result in significant benefits for buyers and sellers and improve sustainable water use. Existing literature on water markets generally takes only buyers’ perspectives into account when studying the factors influencing the purchase of groundwater for irrigation. In contrast, we look at the perspectives of both buyers and sellers to investigate farmers’ participation in informal water markets. We conducted this study in the three agroecological zones of Punjab. The data was collected from a sample size of 360 farmers, with an equal proportion of water buyers, sellers, and self-users. Cragg’s double hurdle model was used to investigate the factors influencing the extent of water buying or selling. Results of the demand side analysis show that educated has negative correlation with water market participation and level of water purchasing. In addition, large farmers are less likely to buy water, indicating that the majority of farmers in water markets are smallholders. However, the degree of land fragmentation, soil fertility, and adoption of improved seeds each have may increase water market participation. Water cost and farmers’ family size has negative impact on level of water purchasing. The results of supply side analysis show that tubewell capacity, degree of land fragmentation, and the number of operational tubewells at a given farm have a positive relationship with the likelihood of selling water. When it comes to the amount of water sold, two factors that positively influence the extent of water selling are the income from water sales and the degree of land fragmentation. Finally, we discuss the implications of these results for sustainable water extraction in the water markets.

Enhancing Food Security through Digital Inclusive Finance: Evidence from Agricultural Enterprises in China

“…According to empirical studies, China has made considerable advancements in the area of food security but has also contributed significantly to environmental contamination through its excessive use of chemical pesticides and fertilizers [ 40 ]. Therefore, it is essential for China’s mode of agricultural development to move toward more effective methods of resource conservation and environmental sustainability [ 40 , 41 ]. Furthermore, the appropriate storage and smooth circulation of agricultural products are also vital for reducing food waste and enhancing food security [ 42 ].…”

Impact of folate biofortified food supplement on rural women's health and willingness‐to‐pay: A study based on a connected randomized controlled trial—Becker–DeGroot–Marschak experiment in China

“…We continued to explore whether consumer valuation is related to sociodemographic characteristics (Razzaq et al, 2022), folate and FFM knowledge, and RCT participation. We applied a Probit regression using whether the subjects' WTP was higher than the average price as the dependent variable on the BDM auction participants.…”

Can agricultural mechanization services narrow the income gap in rural China?

“…The development and improvement of the agricultural mechanization service market can alleviate the financial and land constraints of low-income rural households and enable them to replace direct investment through the roundabout way of purchasing services. Usually, the small and subsistence farmers are not able to make investments in modern agricultural technologies such as water saving technologies for irrigation [ [24] , [25] , [26] ]. However, development of AMS effectively overcomes the contradiction between the small scale of land operation, weak purchasing ability and the demand for high horsepower machinery, and realizes the reasonable allocation of family labor between agricultural and non-agricultural industries [ 27 ].…”
